The Agra Tech Sawtooth Greehouse is a low profile single slope truss. Heated air travels up the roof slope away from the plants.
The two biggest advantages of the Sawtooth design are that it is easy to install exhaust fans mid-house in the vertical wall above the gutter and that it is designed with columns that can continue through the roof to attach an energy truss outfitted with an exterior curtain.
With a vent or opening wall on the windward sidewall and vent on leeward roof, excellent natural ventilation is achieved for happier plants and reduced cooling costs.
Ingolia also has praise for Agra Tech's customer service and expertise. "From the beginning, James Roberts at ATI was our point person," she said. "He was amazing and was more than willing to help us through every aspect of the planning and construction. It was very helpful to be able to rely on James and tap into his extensive knowledge. We asked a lot of questions along the way and he was always there with the answers."
